or the like through the tension device [6 over the guide rod I1, and under the swingably mounted stop wire or member l8. Thence it is led up through the eye of the thread-guide 19 which is secured to the outer end of the traverse frame 20 and is offset laterally to one side of, and spaced beyond the axial zone between the discs 8 and [4. The thread is secured or wound upon itself within the annular space defined by the flanges 8, l2 and I4. To start the winding on the measuring device, the stop and start lever 2! is swung in a direction opposite from that indicated by the arrow until the lug 22 (carried by the arcuate lever 22a secured to lever 2i) engages the shoulder 23- which holds the brake 24 out of engagement in opposition to spring 24a which normally urges the brake into engagement. During the winding of the thread onto the measuring device, the thread passes obliquely as shown in Fig. 2 lengthwise over the periphery of the flange I4.

As shown more clearly in Figure 2 the thread is directed by a guide [9 in such a manner that the thread immediately passes over and off the measuring disc when the space between the disc 8 and the measuring disc I4 is filled to the height of the measuring disc. On account of the offset relationship of the guide with respect to the flange M, the thread T leads off of the windings collected between the flanges, and over the peripheral edge of the flange M in the manner illustrated by the dotted line 28 of Fig. l. Slackness then occurs in the thread T which permits the stop wire [*8 to swing on its pivot and bring the arm 25 into engagement with the cam wheel 26 as shown in ghost outline and thus operate the stopping mechanism of the machine. When this happens the thread becomes slack and this causes the stop member l8 to swing its arm 25 into engagement with the rotating cam wheel 26. This causes sector 21 to lift its shoulder 23 and release lug 22. When this occurs, spring 24a applies the brake 24. This thread or yarn on the measuring disc represents the amount to be stripped from the cake. By varying the overall diameter or the distance between the annular discs any length of yarn may be accommodated in this space. When the machine is stopped after the completion of stripping, the operator severs the yarn and secures the leading end from the cake to the cone and continues with the winding in the usual manner, including the preliminary formation of a transfer tail when desired.

Although this invention has been described with reference to improvements shown, it will readily be appreciated that numerous changes may be made without departing from the spirit and scope of the invention as described in the appended claims.
